CSS employee owners provide on-site support to the Centers for Disease Control and Prevention (CDC) Hazardous Waste Program at several campuses around the country: Atlanta, Georgia, San Juan, Puerto Rico, and Fort Collins, Colorado. With 22 years of experience, CSS staff are responsible for providing training to laboratory and facilities staff to ensure safe handling of hazardous waste to avoid harmful incidents. 

CSS staff provide regular training to CDC staff on topics, including hazardous waste management, using the online waste ticketing system, and spill training. This training covers common mistakes (e.g. improper placement of labels), safety issues (e.g. not including biological materials, improper storage and containment, leaks, and classification), and handling special waste, such as crystalized waste (which can be unstable and possibly explosive). 

Additionally, CSS staff provide universal waste training to CDC staff on an as-needed basis.
